- Arthrogryposis and spinal stiffness are associated with a neuromuscular form of glycogen storage disease type IV (GSD IV).
- Polyglucosan bodies were associated with autophagic material.
- A whole-body MRI pattern with sparing of the medial thigh compartment is described.
Glycogen storage disease type IV (GSD IV) is an autosomal recessive disorder causing polyglucosan storage in various tissues. Neuromuscular forms present with fetal akinesia deformation sequence, lethal myopathy, or mild hypotonia and weakness. A 3-year-old boy presented with arthrogryposis, motor developmental delay, weakness, and rigid spine. Whole body MRI revealed fibroadipose muscle replacement but sparing of the sartorius, gracilis, adductor longus and vastus intermedialis muscles. Polyglucosan bodies were identified in muscle, and GBE1 gene analysis revealed two pathogenic variants. We describe a novel neuromuscular GSD IV phenotype and confirm the importance of muscle morphological studies in early onset neuromuscular disorders.
